Altitude and Tissue Type Influence Antioxidant Potential of Pellia endiviifolia from Darjeeling Himalaya

Abhijit Dey, Arijit De, Pinky Ghosh and Souryadeep Mukherjee    

Abstract: Herbal remedy is considered as one of the popular forms of alternative and complementary medicines. Plants are considered to possess a number of chemical constituents with diverse pharmacological efficacies. Bryophytes, a small group of plants, are known to contain unique secondary metabolites having pharmacological and potential therapeutic value. The primary focus of the study is to depict the role of altitude and tissue types on antioxidant capacity of the liverwort Pellia endiviifolia (Dicks.) Dumort. (Pelliaceae). In the present investigation, an attempt has been made to explore the antioxidative potential of vegetative and reproductive tissues of P. endiviifolia collected from five different altitudes of Darjeeling Himalaya, West Bengal, India. Total phenolics and flavonoids contents of the liverwort samples were also determined. Methanol extract of the thalloid liverwort was investigated for antioxidant activity by DPPH (2,2-diphenyl-1-picrylhydrazyl) radical scavenging activity, total phenolic and flavonoid estimation. Maximum radical scavenging activity was found to be 89.336%±4.3. Maximum total phenolics content in 1 mg of the extract was 58±0.175 μg of Gallic Acid Equivalent (GAE) per mg dry weight. Maximum flavonoids content in 1mg of the extract was 80.3±331 μg of Quercetin Equivalent (QE) per mg dry weight. The results indicate, for the first time, the antioxidative potential and possible use of the liverwort as a natural antioxidant. It also shows a variation of antioxidant capacity of the liverwort depending on their tissue type and their altitude of occurrence.
